hello guys i really ran into a wall with this car and would like to get a second opinion about this issue.

it keeps giving me the CEL code of "misfire #8" I've checked the coil and spark plug by removing them and putting them in the #5 piston and the code persist misfire #8.
There is no oil on the plugs so valve cover gaskets are fine.
Wen I first saw this code I was sure it was going to be a bad coil but now I don't know.
The misfire occurs wen its at idle speeds around 600 rpms.
I've also replaced the cam sensor sense it was one of the original codes.
